The dataset gives the dried weight inpounds of three groups of 10 batches of plants, where each group of10 batches received a different treatment. The Weight variablegives the weight of the batch and the Groups variable gives thetreatment received.
A.) Conduct an analysis of variance to test the hypothesis of nodifference in the weights of the plants under differenttreatments.
B.) Plot and analyze the residuals from the study and comment onmodel adequacy (All tests are to be performed at ? = 0.05)
